Anjana answer is correct and I would like to go into more detail. With server reloads all you are able to do is reload the document in place.
QlikView Publisher allows users to reload data in a QlikView analysis on a periodic basis to ensure that the most current data is available. QlikView Publisher also connects to directory servers within organizations and applies user security rules to a QlikView analysis to ensure appropriate user access. Finally, QlikView Publisher can alert end users to changes to a QlikView file and facilitate distribution via email or a web based interface called AccessPoint.
